Arm Casting
Provides the rigid structural link between major robot joints while routing internal cabling and mounting auxiliary hardware.
Arm castings form the rigid structural links between the robot's major joints, engineered for high stiffness and low weight to keep the arm accurate and responsive without adding unnecessary inertia.
These castings carry internal cable routing, mounting points for auxiliary equipment, and in some designs the counterbalance mechanism, in addition to their structural role.
Damage to an arm casting almost always comes from an external event, a collision, overload, or dropped tooling, rather than gradual wear, since the casting itself does not move relative to its own joints.
